New Direction in Trend in the last 2-5 minutes of a Candle

Hi there ,
from time to time I have been working on my strategy and playing around with some things.
So when my Trading-Session is over I look for more things in the Live-Session to observe new things that improve my profitable System.

What I have observed for the last 3 months is:
The beginning of a New Trend Direction is made in the last 2-5 minutes of a Candle ( for me its the M5 and M15 -TF ).

Is there any Indi that shows ( i.e. M15 ) the last 5 minutes ( in % ) with the comparison of the beginning 10 minutes or is it possible to code such an Indi?
I appreciate any help.
Thanks in advance.

this indi is a part of the request

sorry cannot code

sorry

Thanks for the Indi

If any Coder will have a look to the last minutes ( or lets say play around with seconds may be better ) then it is obvious that the Main-Move and the Move for the next Direction ( which will be following in the next Candle ) is in the last X-minutes or X-seconds.
That depends on the Asset.
Any help is appreciated here.

I wonder that no one find it helpful as this idea is also a spotter for Price Action regarding the smart money.
I know well an experienced profitable Trader from a Bank and I have asked him in which TF's the Traders wait for an intervention in the market and let Price Action and Momentum decide when to make a Trade.
Every TF he mentioned is practicable.

For example a a Candle which become a DOJI -Candle in the last 1-2 minutes is Signal for an Breakout.
You will see this if you have a look for it.
